Just like as
- "US Patent 6701329 - Aging and scavenging of DNS resource records"
- "US Patent 7337910 - Methods and devices for responding to request
for unregistered domain name to indicate a predefined type of service"
(Verisign SiteFinder fiasco)
- "US Patent  6560634 - Method of determining unavailability of an
internet domain name" (Verisign)
- "US Patent  7580982 - Email filtering system and method" (Go Daddy)
- "US Patent 7130878 - Systems and methods for domain name
registration by proxy" (Go Daddy)

Just to list a few.

Be careful the next time you use "vi", somebody may have already
patented that regular expression.
